maven deploy时报错的解决方法

今天在发布maven工程的时候,很奇怪,因为在本地package,install等等都没问题,但是打包的时候就是报错,日志如下:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project courier-rapi: Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter -> [Help 1]

如果对于maven不太熟悉的同学会很苦恼,仔细看日志我们会发现如下的信息:

repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter

意思是在pom文件中缺少distributionManagement标签,或者缺少-DaltDeployementRepositoty,说的是缺少deploy的地址,maven不知道你想要deploy到哪里,在pom文件中增加如下信息,就发布成功了.

    
      nexus
      releases
      http://mvn2.qdingnet.com/nexus/content/repositories/releases
      true
    
    
      nexus
      snapshots
      http://XXXXXXXXXXXXX/nexus/content/repositories/snapshots
    
  

为了补充知识,下面讲解一下关于distributionManagement及其配置的信息.

用于配置分发管理，配置相应的产品发布信息,主要用于发布，在执行mvn deploy后表示要发布的位置,下面时几种配置形式.

配置到文件系统

  
    proficio-repository
    Proficio Repository
    file://${basedir}/target/deploy
  

使用ssh2配置

  
    proficio-repository
    Proficio Repository
    scp://sshserver.yourcompany.com/deploy
  

使用sftp配置

  
    proficio-repository
    Proficio Repository
    sftp://ftpserver.yourcompany.com/deploy
  

使用外在的ssh配置

  
    proficio-repository
    Proficio Repository
    scpexe://sshserver.yourcompany.com/deploy
  


  
    
      org.apache.maven.wagon
      wagon-ssh-external
      1.0-alpha-6
    
  

使用ftp配置

  
    proficio-repository
    Proficio Repository
    ftp://ftpserver.yourcompany.com/deploy
  


  
    
      org.apache.maven.wagon
      wagon-ftp
      1.0-alpha-6
